Double Jeopardy

The Human Body

$400
Secreted by the pancreas, this hormone acts as a key to allow glucose to enter cells, thereby lowering blood sugar levels.
$800
These chemical messengers are produced by endocrine glands and travel through the bloodstream to regulate target cell activity.
$1200
This division of the autonomic nervous system governs the rapid fight-or-flight response.
$1600
Known as the functional unit of the nervous system, this specialized cell transmits information via electrical impulses.
$2000
This gland, often called the master gland, is located at the base of the brain and regulates many other endocrine functions.

Chemistry

$400
This substance acts as a biological catalyst in the body, speeding up chemical reactions without being consumed itself.
$800
This type of chemical bond involves the sharing of electron pairs between atoms.
$1200
This term describes a reaction that absorbs heat energy from the surroundings, resulting in a temperature decrease.
$1600
This principle states that the total mass of substances present remains constant during a chemical change.
$2000

$1600
These dense stellar remnants consist almost entirely of neutrons and possess extremely strong magnetic fields.
$2000
Formed from the collapse of a very massive star, this region of spacetime exhibits gravitational acceleration so strong that nothing can escape it.

Physics

$400
